ABSTRACT:
A liquid crystal display device, by which a reduction of costs of a color filter is realized and declining of the transmittance or reflectance due to an alignment error is suppressed, comprising a pair of substrates arranged facing to each other over a liquid crystal layer, wherein one substrate is formed pixels PXL arranged in matrix. Each pixel is formed a reflection portion for reflecting an outside light and a transmission portion for transmitting a light. The other substrate is formed a color filter colored to be different colors (red, green and blue) corresponding to respective pixels. One or more color adjusting windows CFW having a coloring concentration of zero or less than that of other portions are provided on reflection regions CFR superposing with reflection portions inside pixel regions corresponding to respective pixels.
